利用多种工作模式实现高转换效率的电压型三相半双有源桥DC-DC变换器

A novel high-frequency isolated three-phase voltage-fed semi-dual active bridge dc–dc converter is proposed for unidirectional power flow with wide input variations and high voltage interface. A varying operating mode control independently implemented by phase shift and duty cycle control is subsequently raised to handle the stability and improve the conversion efficiency of the converter under th...
